I dunno if it's the noise that hurts the first shot, as much as the lack of color richness; the loss of color richness, and the loss of overall dynamic range, are the things that really elevated ISO levels seem to impair the most with today's d-slrs. I think the noise is not nearly as objectionable as the weak color, and the lack of richness. I mean, I can see some very even noise...it's even, and not blotchy, and so it's not all "that bad"...it's visible, yes, but not full of chroma noise (not full of colored speckles). But the color is weak, and the image looks pale and washed out.
The composition and the arrangement of the fruit in shot #1 is not too bad though!
